HARRY S. KUHN, OF WAYNESBOBO, PENNSYLVANIA.

VISE.

Application filed November 14., 1910.

I?) all whom it may concern:

Be it known that I, HARRY S. KUHN, a citizen of the United States,residing at l Vaynesboro, in the county of Franklin and State ofPennsylvania, have invented certain new and useful Improvements inVises; and I do hereby declare the following to be a full, clear, andexact description of the invept-ion, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to vises for woodworkers and others; and itconsists in the novel construction and combination of the partshereinafter fully described and claimed whereby the slidable vise jaw isquickly slid to its approximate position by hand and is subsequentlycaused to clamp the work by means of a screw.

In the drawings, Figure 1 is a side view of the vise, partly insect-ion. Fig. 2 is a plan view of the vise, from below. Fig. 3 is arear view of the stop-plate. Fig. 4 is a cross-section through the nut,taken on the line w% in Fig. 1.

A is a stationary or non-slidable vise jaw provided with a bracket B forsecuring it to the underside of any suitable work-bench or support.

C is a movable vise jaw, and D are two rods arranged parallel to eachother and secured at one end to the slidable vise jaw. These rods form aguide for the movable vise jaw and they are slidable longitudi nally inguide holes 03 in the stationary Vise jaw and in the bracket B.

E is a stop-plate which is secured to the free end portions of the rodsD.

F is the operating spindle of the vise which is journaled in theslidable vise jaw C and in the stop-plate E, and which is slidablelongitudinally in a hole f in the stationary vise jaw. The spindle]? isprovided with a handle f.

G is a serrated locking-bar having one end secured to the stationaryvise jaw. The free end portion of the locking-bar is slidable in a hole6 in the stop-plate and may rest lightly on a guard c which projectsfrom the stop-plate.

The operating spindle F is provided with a short screwthreaded portionH, and h is a screwthreaded nut which engages with the screwthreadedportion H. A collar 71/ is secured on the operating spindle at the frontend of the screwthreaded portion, to limit Specification of LettersPatent.

the movement of the nut. The nut 72, has a loop I which incloses thelocking-bar, and this loop has an inclined surface 2'- below theserrated lower side of the lockingbar.

J is a wedge which rests on the surface z' and which is serrated toengage with the locking-bar.

K is a rod which is pivoted to the smaller end portion of the serratedwedge by a pin arranged between the wedge and the stopplate. This nut Nis adjustable, and it is provided with a locking-screw nfor securing iton the rod. This nut N forms an adjustable stop for regulating theaction of the wedge.

When the nut h on the operating spindle is screwed backward toward thestop-plate E the nut N bears against the stop-plate and the serratedwedge is lowered by gravity out of engagement with the locking-bar. Themovable vise jaw together with its guide rods and operating spindle cannow be slid by hand to place the vise jaws at approximately anydesireddistance apart. The operating spindle is then revolved by hand to movethe nut 7b away from the stopplate and toward the collar 7b. Theinclined surface 2' raises the wedge into engagement with thelooking-bar, and the continued revolution of the operating spindle movesthe movable vise jaw so that the vise jaws grip the object between them.When the vise is constructed in this manner only a very shortscrewthreaded portion is required on the operating spindle, and theconstruction is much simplified.

What I claim is:

1. In a vise, the combination, with a nonslidable vise j aw. of amovable vise jaw provided with a guide which is slidable in thenon-slidable vise jaw, a stop-plate secured to the said guide, anoperating spindle journaled in the movable vise jaw and provided with ascrewthreaded portion, a looking bar secured to the non-slidable visejaw. a nut engaging with the said scre-wthreaded portion and providedwith an inclined surthe said wedge and sliclably supported by' the saidstop-plate substantially parallel with the operating spindle andoperating to raise the sald wedge lnto engagement with the locking-bar,and a stop on the said rod between the wedge and the stop-plate, saidstop operating to permit the wedge to move out of engagement with thelocking-bar when the stop is pressed against the stopplate.

2. In a vise, the combination, with a nonslidable vise jaw provided witha supporting bracket, of a movable vise jaw, two parallel guide rodssecured to the movable vise jaw and slidable in the non-slidable visejaw and its bracket, a stop-plate secured to the said guide rods, anoperating spindle journaled in the movable vise jaw and arranged betweenthe said guide rods and provided with a screwthreaded portion, alocking-bar secured to the non-slidable vise jaw, a nut engaging withthe said screwthreaded portion and provided with an inclined surface, aclamping-wedge arranged between the said inclined surface and thelocking-bar, a spring-actuated rod connected to the said wedge andsupported by the said stop-plate, and a stop on the said rod between thewedge and the stop-plate.

3. In a vise, the combination, with a non slidable vise jaw, of amovable vise jaw provided with a guide which is slidable in thenon-slidable vise jaw, a stop-plate secured to the said guide andprovided with a projecting guard, an operating spindle journaled in themovable vise jaw and provided with a screwthreaded portion, a lockingbarsecured to the non-slidable vise jaw and slidable in the stop-plate overthe said guard, a nut engaging with the said screwthreaded portion andprovided with an inclined surface, a clamping-wedge arranged between thesaid inclined surface and the locking-bar, a spring-actuated rodconnected to the said wedge and supported by thesaid stop-plate underthe said guard, and a stop on the said rod between the wedge and thestop-plate.

In testimony whereof I have afiixed my signature in the presence of twowitnesses.
